Radion 9000 is quite old, so it is possible that there are some newer budget cards that have more features and drain less power. If you're unhappy about power consumption, using different GPU might be a better idea. So I'd recommend to avoid modifying any GPU settings (power/clock/whatever). Of course, rendering scenes that used pixel shaders (while cooler was still broken) has been consistently causing surrealistic artifacts (in 3d apps) and corruption of desktop icons (on windows desktop), and system freezes - until cooler has been replaced. To be fair, last cards I had were relatively resitant to overheating - one GF8400GS worked for a month with broken cooler without noticeable permanent damage. I'd strongly recommend to avoid overclocking GPU, becuase it'll be easy to fry or permanently damage it. However, there's no cross-platform API, and settings are probably extremely GPU-specific. Judging from results of google search, nvidia provides API for overclocking their GPUs, and there are some ATI tools available as well (though ATI tools look 'unofficial'). On the clock, 1825mhz memory and 10 on power.

Any ideas using the Nvidia or ATI SDK maybe? Rx 480 Max Temp MSI RX 480 Gaming X: 48C: 73C: 31 dBA: ASUS RX 480 STRIX: 38C: 68C: 39 dBA: AMD RX.
